1)  color gradient
颜色梯度
1.
Based on 395 late-type spiral galaxies brighter than 15 mag in r-band that selected from Data Release Two of Slogan Digital Sky Survey, we decompose their bulges and disks through one-dimensional fitting of the surface brightness profile, and statistically analyze the color gradients in their disks.
从Sloan巡天第二批释放的数据(Sloan Digital Sky Survey, Data Release Two)中选择了395个在r波段亮于15 mag的晚型旋涡星系作为样本,对样本星系的表面亮度轮廓进行一维两成分(核球与盘)拟合,并着重讨论了盘的颜色梯度,分别用Δc/ΔR和Δc/Δlg R两种形式来拟合。
2.
The color gradient of spiral galaxy freezes its fossil information of the star formation history along the disk and therefore provides a strong constraint on the models of disk formation and evolution.
旋涡星系的颜色梯度反映了其星族构成沿径向的分布,包含了星系恒星形成历史的信息。
2)  color and gradient feature
颜色和梯度特征
1.
Based on the fusion of color and gradient features, this paper implements a novel approach to real-time background subtraction.
通过融合图像的颜色和梯度特征,实现了一种实时背景减除方法·首先融合颜色和梯度特征建立新的能量函数;然后基于图切割算法最小化能量函数,并对前景/背景进行分割;最后使用光流验证前景区域的真实性,并更新背景模型·对不同场景的实验结果表明:该方法可以实时地检测出视频序列中的运动物体,结果准确、有效
3)  radial color gradient
径向颜色梯度
1.
We investigate their radial color gradients and the correlation between the color gradient and the basic parameters, for example, the size, luminosity (stellar mass), surface brightness (surface mass density), and concentration parameter.
文中对这些星系的径向颜色梯度颜色梯度与星系基本参量(大小、绝对星等、面亮度等)的依赖关系进行了统计研究。
4)  color ratio gradient(CRG)
颜色比率梯度(CRG)
5)  Color-Directional Gradient Angular Histogram
颜色-梯度方向角直方图
6)  Color Density
颜色密度
